IMPROVEMENT IN COCKS.

Specification forming part of Letters P To all whom it 'may concern:

Be it known that I, J. P. GALLAGHER, of St. Louis, in the county of St. Louis and State of Missouri, have invented a new and useful Improvement in Cocks or Faucets; and I do hereby declare that thefollowingis a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the saine,reference being had to the accompanying drawings, forming part ot this specification.

Figures 1 and 2 are longitudinal central sections of my invention.

This invention relates to a new and usel'ul means for allowing of the escape ot' waste water from cocks, faucets, Src., to prevent the freezing up ofthe same during winter.

A represents the body or main portion ot' a cock or faucet, and Bis a rising and falling valve placed in A and operated by a screw, a, alve passing up through a D, and through a cap, E, wn in both tgures.

chamber or barrel, on the top of D, as sho F represents a tube, which forms a communication between the body A ot' the cock at the rear of valveB and the chamber or barrel D.

G is a circular disk titted within the cap E` and having a grooved periphery, b, and also a pendent concentric tube, c, through which the valve stein O passes, the stem also passing through the disk G. This groove b forms a water-passage all around G and obviates any difficulty which might otherwise occur from the turning of the disk in the cap. The tube c is larger in diameter internally than the stein C, so as to aord a water-passage up between O and the interior of o, and the interior ot' the tube c communicates with the groove b in the periphery of the disk G by means of a hole or opening, d. (Shown in both figures.)

H is a tube, which is in line with the groove disk is provided with in order that it may tit air and wab of the disk G, and this packing e,

atent No. 48,673, dated July 1i, 1865.

The valve B is virtually two valves, as both its upper and lower surfaces act as such, the latter surface,f, when the valve is down closing the body or main portion A ot' the cock or faucet, as shown in Fig. 1, and the upper surface,j", when the valve is raised closing the lower end the tube c, as shown in Fig. 2.

From the above description it will be seen thatwhen the valve B is closed so as to stop the tlow of water through A, the waste Water at the rear of the valve will pass up through the tube F and enter the chamber or barrelD above the valve, and thence pass up into tube c through the hole or opening L into groove I), and thence'out through tube H, as shown by the red arrows in Flg.1; and it will further be seen that when the valve B is raised or opened the upper surface of the valve will close the lower end ot' tube c and stop the escape ot' water through H while the discharge is allowed through A, as will be fully understood by referring to Fig. 2.

Thus by this simple means a free escape is allowed the Waste water each time the cock is closed or the iiow through it stopped and all difficultyY from freezing avoided.

I claim as new and desire to secure by Letters Patentl. The tube F, arrange body A of Ythe cock or faucet, and the chainber or barrel D and the valve B,`in connection with the tube c, disk G, and escape-spout H, substantially as and for the purpose specified.

2. The groove b in the periphery ot` disk G, when used in connection with the parts specified in the first claim,for the purpose of affording an annular chamber around the disk G, as described.
